  41. The Extended Industry Standard Architecture (EISA) bus was
  42. developed as an open alternative to the IBM MicroChannel bus.
  43. The EISA bus provided some of the features of the IBM MicroChannel
  44. bus while maintaining backward compatibility with cards made for
  45. the older ISA bus. The EISA bus saw limited use between 1988 and
  46. 1995 when it was made obsolete by the PCI bus.

  61. modems or hard drives often used with laptops computers. There are
  62. actually two varieties of these cards: the older 16 bit PCMCIA cards
  63. and the newer 32 bit CardBus cards. If you want to use CardBus
  64. cards, you need to say Y here and also to "CardBus support" below.
  65. To use your PC-cards, you will need supporting software from David
  66. Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
  67. for location). Please also read the PCMCIA-HOWTO, available from

  77. (3/50, 3/60, 3/1xx, 3/2xx systems). Enabling this option requires
  78. that all other hardware types must be disabled, as Sun 3 kernels

  247. At some point in the future, this will cause floating-point math
  248. instructions to be emulated by the kernel on machines that lack a

  256. The fpu uses normally a few bit more during calculations for
  257. correct rounding, the emulator can (often) do the same but this
  258. extra calculation can cost quite some time, so you can disable
  259. it here. The emulator will then "only" calculate with a 64 bit
  260. mantissa and round slightly incorrect, what is more then enough
  261. for normal usage.
  262. config M68KFPU_EMU_ONLY
  263. bool "Math emulation only kernel"
  264. depends on M68KFPU_EMU
  265. help
  266. This option prevents any floating-point instructions from being
  267. compiled into the kernel, thereby the kernel doesn't save any
  268. floating point context anymore during task switches, so this
  269. kernel will only be usable on machines without a floating-point
  270. math coprocessor. This makes the kernel a bit faster as no tests
  271. needs to be executed whether a floating-point instruction in the
  272. kernel should be executed or not.

  276. This gives you access to some advanced options for the CPU. The
  277. defaults should be fine for most users, but these options may make
  278. it possible for you to improve performance somewhat if you know what
  279. you are doing.
  280. Note that the answer to this question won't directly affect the
  281. kernel: saying N will just cause the configurator to skip all
  282. the questions about these options.

  284. config RMW_INSNS
  285. bool "Use read-modify-write instructions"
  286. depends on ADVANCED
  287. ---help---
  288. This allows to use certain instructions that work with indivisible
  289. read-modify-write bus cycles. While this is faster than the
  290. workaround of disabling interrupts, it can conflict with DMA
  291. ( = direct memory access) on many Amiga systems, and it is also said
  292. to destabilize other machines. It is very likely that this will
  293. cause serious problems on any Amiga or Atari Medusa if set. The only
  294. configuration where it should work are 68030-based Ataris, where it
  295. apparently improves performance. But you've been warned! Unless you
  296. really know what you are doing, say N. Try Y only if you're quite
  297. adventurous.

  308. ---help---
  309. The 68060 generally uses copyback caching of recently accessed data.
  310. Copyback caching means that memory writes will be held in an on-chip
  311. cache and only written back to memory some time later. Saying Y
  312. here will force supervisor (kernel) accesses to use writethrough
  313. caching. Writethrough caching means that data is written to memory
  314. straight away, so that cache and memory data always agree.
  315. Writethrough caching is less efficient, but is needed for some
  316. drivers on 68060 based systems where the 68060 bus snooping signal
  317. is hardwired on. The 53c710 SCSI driver is known to suffer from
  318. this problem.

  539. Even if you say Y here, the currently visible virtual console
  540. (/dev/tty0) will still be used as the system console by default, but
  541. you can alter that using a kernel command line option such as
  542. "console=ttyS1". (Try "man bootparam" or see the documentation of
  543. your boot loader (lilo or loadlin) about how to pass options to the
  544. kernel at boot time.)
  545. If you don't have a VGA card installed and you say Y here, the
  546. kernel will automatically use the first serial line, /dev/ttyS0, as
